Abstract

A drive system is taught for controlling the modal content of drive signals used to excite drives on a vibrating conduit, such as in a Coriolis mass flowmeter or a vibrating tube densimeter. Motion signals are obtained from spatially distinct feedback sensors. A modal response signal corresponds to one of the vibration modes at which the vibrating conduit is excited. Modal response signals are input to a drive channel, each having a separate processing channel. Within each channel, the respective modal response signal is compared to a desired modal response setpoint.
The resulting mode error signal is amplified to produce a modal excitation signal for each mode. The modal excitation signal, representing the modal excitation applied, is transformed from the modal domain back to the physical domain and mapped to physical locations of the drives. The resulting drive signals are applied to the drives to excite the conduit.
